In the I Love Lucy episode Never Do Business with Friends, S2, #67 6/29/53, we get a rare opportunity to see the Mertzes’ kitchen. Apparently the set of the Ricardo’s kitchen could be used, with some modifications, as the Mertz kitchen.  In the screen capture above there are kitchen cabinets under the window, where Lucy had a stove and to the right are shelves similar to those in Lucy’s kitchen. On an upper shelf are some Brock of California, Chanticleer pattern plates and on the shelf below there appears to be a matching Brock bowl. Below that on the counter top sits an Accent shaker set as seen in Lucy’s kitchen usually positioned on top of the stove.

(Thanks to Rickster for spotting the plates!).
